6. Bicycle crunches
Make sure you engage your abs and twist from your core. Your goal is 3 sets and for each set you’ve got to complete 10 bicycle crunches with each leg.
STEPS:
1. Lie flat on your back, hands behind your head and your knees towards your chest.
2. Straighten your right leg out to a 45-degree angle and bring your right elbow towards the left knee.
3. Now switch sides and repeat on the other side to complete one rep.
